Application October 8,

3 Claims.

This invention relates toseals for application to metal straps or hoops for boxes, barrels and bales.

An object is to provide a seal having certain portions thereof punched so that the same can be more readily applied to hoops or bands without the necessity of employing a shearing tool. A further object is to provide a beaded hoop or band and a cooperating beaded seal for application thereto.

Referring tothe drawing, which is made a part of this application and in which similar reference characters indicate similar parts:

Figure 1 shows a precut seal in blank form,

Figure 2 illustrates a joint in a hoop or band to which the seal of Figure 1 has been applied,

Figure 3 shows a precut seal bent into channel form and provided with a bead for cooperation with a beaded hoop or band, and

Figure 4 shows a section of a barrel having a double headed hoo-p and seal applied thereto.

Fig. 1 is a plan view of a pre-punched seal in which a plurality of slits have been made in a piece of metal in such location with respect to each other that when the seal is applied to a hoop all that is necessary is to push the slitted portions of the seal into the metal of the hoop thereby deforming the hoop and providing an eflicient locking device. By the use of this type of seal it is not essential that the tool applying the same shall necessarily have any shearing action although a shearing tool can be applied to this type of seal as effectively or more so than where the seal has not previously been sheared.

Fig. 3 shows a seal of the type shown in Figures 1 and 2 with the additional feature that a bead has been formed in the center portion thereof to cooperate with a beaded hoop. This ligure also shows the seal bent into U-shape ready to be applied to the hoop or band by the sealing tool.

Fig. 4 shows a hoop provided with two beads and a seal applied thereto in locked position. In this ligure the seal also has two beads to cooperate with those of the hoop in order that the parts may come into direct contact when the seal is applied. 'I'he hoop is also shown applied to a portion of a barrel with the hoop attached to the barrel staves by means of nails whichare usually driven through the staves from the inside of the barrel and have their ends or points coming out between the beads of the hoop and clinched thereon.

Fig. 1 shows a seal blank which has been By pre- 1931, Serial No. 567,695

(Cl. 2li-23) cutting the seal at the places indicated in Fig. 1 it is rendered easier of application to a band or strap since the tool used for applying the seal will not have to performv the work of shearing the seal but merely that of distorting the band.

Fig. 2 shows-a seal of the type shown in Fig. 1 applied to the portions @it and l5 of a strap or hoop. The underside of the seal is shown in thisfigure with the portions 46 bent backwardly. When the portions i6 are bent out of the plane of the back of the seal they tear or deiorm the edges of the hoop and lock them to the seal. Fig. 3 shows a seal substantially the same as that shown in Figs. 1 and 2 which however is provided with a groove il for application to a hoop having a single bead. It is apparent that the same type of seal may be applied'to a double beaded hoop as illustrated in Fig. 4 by providing two grooves of the type shown at lll in Fig. 3. In Fig. 4 there is shown a double beaded hoop 48 to which has been applied a seal 9. This seal is of the type just referred to and is provided with two grooves to t the two beads of the hoops 5B and 5|. The seal t9 may be punched or pre-cut in accordance with the teaching of Fig. 1 or it may be made from an uncut seal provided with two grooves. In Fig. 4 the hoop is shown as applied to a number of barrel staves 52, 53 by means of nails, the ends of which are shown at 54 clinched against the outer side of the hoop and in contact with one of the beads. This type of hoop is very useful where it is necessary to nail the hoopy tol the barrel staves and the beads thereon serve effectively to prevent injury to articles coming into contact with the side of the barrel by reason of the outstanding beads on the outer surface of the hoop.

It will be seen from the above description and drawing that a seal has been provided which is easy of application and effective to provide a locked joint in bands and hoops of the character under consideration. The seal may be readily made by simple stamping and punching operations and in its application it is only required that the metal of the strap be sheared since the slits in the seal are precut and the parts thereof are deformed by a simple pressing operation to be brought into locking engagement with the band or hoop.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent is:

l. An elongated channel shaped clip for sealing straps or hoops, comprising a body portion and two parallel ange portions forming the sides of the channel and defining at their junction two parallel corner edges each corner edge having a plurality of parallel slits therethrough transversely of the length of the clip, said slits extending into the body portion and into the flange to dene portions of the clip to be distorted in application of the clip to a strap or hoop the adjacent edges of the slitted portions being in Contact throughout the length of the slits.

2. An elongated channel shaped metal clip for sealing straps or hoops, comprising a plane body portion and two parallel plane ange portions forming the sides of the channel and defining at their junctions with the body portion two parallel corner edges, each corner edge having a plurality of parallel slits therethrough transversely of the length of the clip, said slits extending into the body portion and into the flange to define portions of the clip to be distorted in application of the clip to a strap or hoop, the body portion of the clip being provided lengthwise with a bead to conform to a corresponding bead on the strap or hoop.

3. An elongated metal clip for sealing straps or hoops, comprising a blank having two sets of parallel slits therein and spaced apart length- Y wise of the clip, said slits lying whollywithin the confines of the blank and defining portions of the clip which are to be distorted in applying the clip to a hoop or strap, the portions to be distorted alternating with other portions not to be distorted and in contact with said portions throughout the length of the slits, all said portions between the slits being at their ends integral with the body of the clip.
